public class StringLike

extends StringOperator

implements BinaryOperator

A class for representing "like" operator that is operated on the supplied two strings. It accepts two strings firstString and secondString. The evaluation of this operator should return true if ((firstString.toUpperCase()).indexOf( (secondString.toUpperCase())) > -1), otherwise return false.

Method Detail

getLeftHandSide

public Object getLeftHandSide()

Description copied from interface: BinaryOperator

Returns left hand side operand of this binary operator.

Specified by:

getLeftHandSide in interface BinaryOperator

Returns

The left hand side operand.

getRightHandSide

public Object getRightHandSide()

Description copied from interface: BinaryOperator

Returns right hand side operand of this binary operator.

Specified by:

getRightHandSide in interface BinaryOperator

Returns

The left hand side operand.

getParameterSignature

public Class[] getParameterSignature()

Description copied from interface: Expression

Returns the parameter signature for this Expression. Because the sub-expressions within the Expression are typically arguments or operands, some type validation is performed by examining the class types of the sub-expressions against the Expression's parameter signature.
The tests that are performed are:
1. The number of sub-expressions must equals the number of parameter entries.
2. The class type of any sub-expression (or the result of evaluating the sub-expresssion) must equal the class type of the corresponding parameter entry.
3. Any null parameter entries are ignored and are considered optional sub-expressions.

Specified by:

getParameterSignature in interface Expression

Returns

the Class array containing the parameter signature.

isCaseInsensitiveMatch

public boolean isCaseInsensitiveMatch()

equals

public boolean equals(Object o)

Override to check the caseInsensitiveMatch flag as well.

Overrides:

equals in class com.bea.p13n.expression.internal.ComplexExpressionImpl

hashCode

public int hashCode()

Override to check the caseInsensitiveMatch flag as well.

Overrides:

hashCode in class com.bea.p13n.expression.internal.ComplexExpressionImpl
